A bending machine with a controlled-return bending die includes a matrix (2) mounted around a spindle (3) having an axis y, a bend arm (4) being able to turn around on the same axis y, and a vice (5) adapted to clamp a section of a workpiece to be bent. Driving means causes the bend arm (4) and the matrix (2), both being connected together by the vice (5), to rotate around the axis y for a set angle from a start position, and a workpiece bending operation is performed for a workpiece section corresponding to said angle. The bend arm (4) carries on itself a controlled return means able to return said matrix (2) to its start position at the end of workpiece bending operation.
